EMILE' F.4 CAZALET, OF KENTLAND, INDIANA;

GRAIN PURIFIER AND DRIER.

SPECIFICATION forming part of Letters Patent No. 592,691, dated October 26, 1897. Application filed April 20, 1897. Serial No. 63,023. (No model.)

Indiana, have invented a newand useful Purifier and Drier for Oats and other Grain, of which the following is a specification.

This invention aims to increase the marketable value of oats and other grain without materiallyincreasing the cost of the purifying operation, and in accordance with this invention the oats are whitened, purified, cleaned, and sweetened, as all musty and close smell is removed and germs killed.

In carrying out the intent of this invention the oats or grain to be treated are subjected to sulfurous fumes in the presence of moisture, the latter being supplied in the form of steam, which causes the fumes to combine with the shell of the grain and bleach it and remove all trace of mustiness or other odor' tending to depreciate the value of the grain and showing an inception of deteriorating. The steam also causes the fumes to circulate through the casing and carries off the objectionable matter removed from the grain during the purifying and bleaching operation,

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawing and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without .de` parting from the principle or sacrificing any of the advantages thereof, and to afull disclosure of the invention an adaptation thereof is shown in the accompanying drawing, which is a vertical central section of an apparatus for carrying into effect the purposes of this invention.

The casing 1 is a box-like structure of considerable length and presentingthe appearcates with the upper end of the casing-and a spout 3 projects from its bottom and provides and escape for'the oats or grain when purified. An inclined board 4 is located at the lower end of the casing and corresponds in position with the lowest element of the spout 3 to prevent the lodging of the grain in the angular space formed between the bottom of A ventilator 2 communii the casing and the side remote from the spout.

`A series of bars are located at intervals in the length of the casing and are spaced apart any desired distance, so as to secure a thorough loosening, agitation, and turning of the grain in its descent through the casing, besides serving to retard the movement of the grain, whereby it receives the full benefit of the sulfurous fumes and steam-bath. The bars are disposed in tiers or courses and are arranged alternately, or, in other words, are provided in two sets or series, the bars of one set or series crossing at right angles to the bars of lthe other set or seriesfas clearlyindicated in the drawing. The bars 5 of each set or series are disposed to break joint, whereby the grain is interrupted in its descent, so that every part will be subjected to the action of the fumes and vapor. A gate 6 controls the `spout 3 and a trough 7 communicates with the said spout and is provided with a conveyer 8, by means of which the oats or grain are positively moved through the trough to thedesired point of discharge.

An inlet 9 is provided ina side of the casing at its upper end and the oats or grain to be treated are supplied thereto directly from the elevator or in any way found most advantageous to the successful operation of the invention. A pipe 10 communicates with a side of the casing a short distance from its lower end and leads to a furnace 11,in which the sulfur is burned to generate the fumes to be utilized in the treatment of the oats or grain tobe purified Vand bleached. This pipe is supplied with a damper 12 for regulating the supply of fumes or cutting off the same when desired. A steam-pipe 13 communicates with the pipe l0 and has connection with a steam-boiler or other generator (not shown) and in the operation of the invention creates a blast through the pipe 10 to carry therethrough the sulfurous fumes from the furnace 11, whereby the said fumes are carried into the casing and are caused to pass upwardly therethrough in an inverse direction to the descent of the grain gravitating therethrough. The steam from the pipe 13 acts as a twyer and sucks the fumes from the furnace 11 and forces theminto and through the casing and is the agent which causes the fumes to combine with the grain, whereby TOO the shell or covering is bleached, all dampness and musty odors removed, germs killed, and the grain otherwise puriiied and reduced to a marketable condition at an expense about equal to that required for cleaning grain as generally practiced and with the additional advantage of materially increasing the value ef the grain by bleaching, sweetening, and removing all smell and noxious odors.

From the foregoing it will be understood that the process is continuous, the grain entering at 9, passing through the apparatus, and escaping at 3. The height of the casing must be such that the grain in its travel therethrough is wh itened, purified, and sweetened, the bars 5 serving to materially retard the passage of the grain through the apparatus, so that itis kept in contact with the fumes and steam for a longer period than if not interrupted in its descent. The rebounding of the grain on the bars 5 produces an agitation and causes all parts of the grain to be exposed and subjected to the sulfurous fumes and steam, thereby insuring satisfactory and thorou gh results.

Having thus described the invention, what is claimed as new isl. An apparatus for treating oats and grain for purifying, sweetening and whitening the same, consisting of an'iupright casing having an inlet at its upper end and an outlet at its lower end, and provided at intervals in its length with bars for retarding the passage and agitating the grain, a pipe communicating with the lower portion of the casing and having connection with a furnace or other device for generating sulfurous fumes, and a steam-pipe communicating with the aforesaid pipe for creating a blast therethrough and positively circulating the fumes through the casing7 substantially as and for the purpose set forth.

2. The herein-described apparatus for treating oats and grain, consisting of an upright casing having an inlet at its upper end and a spout at its lower end provided with a cut-oit, an inclined board at the lower end of the easing-and about in line with the lowest element of the spout, a trough provided with a conveyer in communication with the said spout,

a ventilator at the upper end of the casing,'

two sets of bars alternately disposed at intervals in the length of the casing, asupply-pipe communicating with the lower portion ot the A easing and having a damper and in communication with a furnace for generating sulfurous fumes, and a steam-pipe communicating with the su pply-pipe for creating a blast therethrough and causing the fumes to circulate positively through the casing, substantially inthe manner set forth for the purpose specifled.

In testimony that l claim the foregoing as my own l have hereto affixed my signature in the presence of two witnesses.
